WATER-WH EEL.

SPECIFICATION forming part of Letters Patent No. 518,599, dated April24,1894. Application filed December 80,1892. Serial No. 456.813. (N0model.)

To all whom it may concern.-

l 3e it known that 1, ANDREW J. GOULD, a citizen of the United States,residing at Quincy, in the county of Plumas and State of Cali-. fornia,have invented a new and useful Water-Wheel, of which the following is aspecification.

This invention relates to water wheels of that class having bucketssecured to the periphery of the wheel and receiving the impact of astream of water under pressure from a nozzle, and the same is designedas an improvement on Letters Patent No. 291,894, granted to me January15, 1884; and it has for its primary object to provide a wheel that willeffectively prevent any loss of power from back pressure and which is soconstructed, as set forth by this improvement, that the same willpresent a bucket of sufficient capacity to receive a full head of waterdirected therein.

With these and many other objects in view which will present themselvesto those skilled in the art, the invention consists in the novelconstruction of water wheel buckets hereinafter more fully described,illustrated and claimed.

In the accompanying drawings;*Figure 1 is a perspective view of a waterwheel constructed in accordance with my invention. Fig. 2 is a detail inperspective of one of the buckets and a portion of the wheel to whichthe same is connected, part of the bucket being broken away to exposethe interior construction. Fig. 3 is a detail front elevation of one ofthe buckets and the portion of the wheel to which the same is attached.Fig. 4: is a detail plan view of one of the buckets.

Referring to the accompanying drawings; A represents the water wheeladapted to be mounted upon a horizontal shaft and which is of anysuitable constructionand material. The flat rim or periphery of saidwheel is provided around its entire length with a series of inclinednotches or indentations B which are so constructed as to form straightback walls I) and the forwardly extending diverging side walls I).

Located directly over each of the notches or indentations upon theperiphery of the wheel are the series of water buckets C which may beeither integrally cast with the water wheel proper or are securedthereto as illustrated in the drawings, by a single set of screwspassing through the body thereof and entering the periphery of thewheel. Each of said buckets G is provided with a solid portion 0 havinga straight wall 0 and forwardly extending diverging side walls a, saidstraight back wall and the diverging side walls registering with theback and side walls respectively formed in the periphery of the wheeland extending above the same, thus forming a single back and side wallshaving an increased impact surface against which the stream of waterplaysand is discharged therefrom, being of sufficient size to receivethe full head or stream of water directed therein from a nozzle, asillustrated in my former patent. The said buckets are also provided withthe forwardly extended inclosing top plates D from the forward end ofwhich depend the integral division walls E bearing or resting upon theperiphery of the wheel beyond the indentations B and converging inwardlytoward the straight back walls of the buckets, thus forming the centralwater receiving openings F and the enlarged lateral escape or dischargeopenings G, the angle of said division walls corresponding to the angleof the side walls in the bottom of the buckets. It can be readilyseen,from the construction of the rear or-inner walls of the buckets, that anincreased impact surface is formed for the stream of water to playagainst and thereby provides an additional bucket capacity whichaccommodates a large head of water, while the dispositin of the lateralescape openings provides for a free discharge of water which also at thesame time materially assists in turning the wheel and eifectuallyprevents back pressure. 7

It will be obvious that the construction herein described provides animproved water bucket, a part of which is formed in the solid body ofthe rim of the wheel, thereby securing several points of advantage overmy former patent. In the first place it is to be noted that in thepresent construction the projectin g part of thebucket does not extendbeyond the periphery of the wheel a greater distance than the projectionof the old form of bucket shown in my former patent, but in the presentconstruction the bucket, as an entirety,

is made much deeper and can therefore aecommodate a jet from a'nozzleofgreaterdh ameterthan the nozzle which must be e111- ployed, to force ajet or stream ofmwater into 5 the 01d bucket.

of the wheel'are not at all increased,--while the jet-receivingcapacityof the buckets of the wheel-is materially increased-.-; Further? tomore, sincethe jet is arranged to strikethe entire Width of the backwallof the bucket 1 at right angles, the strong-rim of the Wheel bears itsshare of the "force; of the jet, and therefore relieves theprojectingpart of the 15 bucket of much strain, consequently'provid-j inga muchstronger bucketthantheone" claimedin my old patent, and still anotherpoint is to be observedin the factthat by reason of the increased depthof the new 20 bucket herein described, the resistance to the adischarging water is greatly'lessenedandthe free and easy discharge.greatly irnproved.

Having thus described my invention, What r I claim, and desire to secureby Letters Pat- 2 5 cut, is-

As an improvement in water Wheels, the
